Specifically, the gear of the indoor fan can be increased. For example, the mute gear is adjusted to the low wind gear, the low wind to the medium wind gear, the medium wind to the high wind gear, and the high wind to the power gear. Thus, the anti-freezing protection of the air conditioner is facilitated.
Optionally, the preset temperature threshold value ranges from [0 ℃, 3 ℃). More specifically, it may be 0 ℃, 1 ℃, 2 ℃ or 3 ℃. In this way, the preset temperature threshold value is set in a proper range, so that the anti-freezing operation is favorably carried out at a proper time.
Fig. 3 is another control method for an air conditioner, which may be executed in the air conditioner or in a server communicating with the air conditioner, according to an embodiment of the present disclosure, where a case is described with a processor of the air conditioner as an execution subject.
As shown in fig. 3, the control method for an air conditioner includes:

Therefore, the situation that the related anti-freezing operation cannot be triggered due to the fact that the temperature of the indoor coil cannot reach the preset temperature condition can be effectively avoided, and therefore more comprehensive anti-freezing protection is facilitated. In addition, the defrosting result can be automatically detected, and the air conditioner is controlled to enter a further defrosting process or be restored to a normal operation state according to the detection result.
Optionally, the preset time interval has a value range of [1min, 5min ]. More specifically, it may be 1min, 2min, 3min, 4min or 5 min. Therefore, the time interval is limited in a proper range, the frosting condition on the surface of the indoor evaporator caused by too small time interval can be avoided, resources are wasted, and the condition that the defrosting result cannot be timely judged due to too large time interval can be avoided, so that the defrosting process is carried out for a long time.

Wherein, the preset times can be 2 times, 3 times and the like. The condition that the defrosting effect is not ideal for multiple times can indicate that the air conditioner has a fault, so that the fault prompt is sent to prompt a user to overhaul the air conditioner in time.
Alternatively, the first failure prompt and the second failure prompt may be the air conditioner emitting a prompt tone, and/or the failure sign is displayed on the screen of the air conditioner. Therefore, fault prompt can be realized only by the air conditioner, other equipment is not needed, and the method is simple and feasible.
Optionally, the first fault prompt and the second fault prompt may also be sent by the linkage of the air conditioner and the mobile terminal or other intelligent devices. For example, a fault prompt is sent to a smart phone or a smart computer of the user, and a recommended measure is sent.

Therefore, the prompt information can be ensured to be received by the user in time, and the subsequent processing can be carried out in time. In addition, more information can be provided for the user, and the user can grasp the actual situation.
Here, the first failure indication should be different from the second failure indication. Therefore, the user can directly determine the actual situation according to the received prompt, and confusion is avoided.

By adopting the control method for the air conditioner provided by the embodiment of the disclosure, at least the following technical effects can be realized: because the influence of the small-area frost formation on the heating process is small, the defrosting is not needed. Therefore, the defrosting is carried out only under the condition that the frosting area exceeds the preset value, so that redundant operation is reduced, false defrosting is effectively avoided, and energy consumption is saved.
Optionally, the processor obtaining a frosted area of the outdoor heat exchanger surface comprises: and the processor obtains the image of the surface of the outdoor heat exchanger sent by the detection device and determines the frosting area according to the pre-stored frosting characteristics. Therefore, the frosting condition of the outdoor heat exchanger can be visually and accurately determined, and the defrosting of the outdoor heat exchanger at a proper time is facilitated.
Alternatively, the preset value may be 50% of the visible area of the detection device. Similarly, it may be 40%, 60%, etc. of the visible area of the detection device. Like this, can avoid the default too little to lead to carrying out the defrosting operation under the unnecessary condition, can avoid the default too big again to lead to can not carrying out the defrosting even, influence the user and use.

Therefore, the defrosting is carried out only under the condition that the frosting area exceeds the preset value, so that redundant operation is reduced, false defrosting is effectively avoided, and energy consumption is saved. In addition, the defrosting time of the air conditioner is determined according to the outdoor environment temperature and the running time of the air conditioner, so that the accurate defrosting time can be determined, and the defrosting effect can be improved.
Optionally, the determining, by the processor, a defrosting time of the air conditioner according to the outdoor ambient temperature and the operation time of the air conditioner includes: under the condition that the outdoor environment temperature is less than or equal to a first preset temperature, if the operation duration is less than the first operation duration, the processor determines to defrost after the first defrosting time; under the condition that the outdoor environment temperature is greater than the first preset temperature and less than or equal to the second preset temperature, if the operation duration is less than the second operation duration, the processor determines to defrost after the second defrosting time; under the condition that the outdoor environment temperature is greater than the second preset temperature and less than or equal to a third preset temperature, if the operation time length is less than a third operation time length, the processor determines to defrost after the third defrosting time; under the condition that the outdoor environment temperature is greater than the third preset temperature and less than or equal to the fourth preset temperature, if the operation duration is less than the fourth operation duration, the processor determines to defrost after the fourth defrosting time; and under the condition that the outdoor environment temperature is higher than the fourth preset temperature, the air conditioner continues to operate. The first preset temperature is lower than the second preset temperature, the second preset temperature is lower than the third preset temperature, and the third preset temperature is lower than the fourth preset temperature. The first operating duration is greater than the second operating duration, the second operating duration is greater than the third operating duration, and the third operating duration is greater than the fourth operating duration. The first defrosting time is longer than the second defrosting time, the second defrosting time is longer than the third defrosting time, and the third defrosting time is longer than the fourth defrosting time. In this way, the exact time for defrosting can be entered.
